Description
Technical Field
The utility model relates to the technical field of soilless culture, in particular to an ozone disinfection device for soilless culture nutrient solution.
Background
Currently, modern agricultural equipment is utilized, environmental parameters of each link of plant growth, such as moisture, nutrition, carbon dioxide concentration and the like, are regulated and controlled through manual intervention, and optimal growth conditions are provided for the growth of crops, so that the method has become a main production mode for producing high-quality agricultural products. In this process, nutrient solution is one of the keys, and maintaining the environmental health of nutrient solution is a serious issue in producing high quality agricultural products. However, in actual production, pathogenic microorganisms (bacteria, fungi, viruses) and phytoplankton (algae) are present in the nutrient solution in the open production environment, and small-particle plant residues may be present in the hydroponic environment and the recycled nutrient solution. These factors may all lead to diseases of cultivated plants, physiological diseases or pathological diseases, and influence the production of high-quality vegetables. Therefore, in order to ensure continuous and stable production of high-quality vegetables, the sterilization of the nutrient solution is particularly important.
The method for sterilizing the nutrient solution mainly comprises 4 modes of high-temperature sterilization, oxidant sterilization, ultraviolet sterilization and filtration sterilization. The nutrient solution is often required to be heated to more than 90 ℃ for high-temperature sterilization, so that the sterilization effect is excellent, but the energy consumption is higher; oxidant disinfection often uses strong oxidants such as sodium hypochlorite and ozone, which are ideal disinfectants due to their high efficiency and cleaning characteristics, but are limited in practical use due to their instability; ultraviolet sterilization requires that ultraviolet rays irradiate pathogenic microorganisms, but in practical application, tiny particulate matters in the nutrient solution can block the ultraviolet rays, so that the pathogenic microorganisms are not ideal in sterilization effect; the filtering and sterilizing process utilizes the filtering membrane with different apertures to filter, but only can filter specific pathogenic microorganisms, so that the nutrient solution is not thoroughly sterilized.
Ozone has a solubility in water of 13 times higher than that of oxygen, a sterilization rate of 600 times that of chlorine and 1000 times that of ultraviolet rays, and is widely used in various fields such as medical treatment, food, water treatment, agriculture and the like. Research shows that the higher the ozone concentration, the better the microorganism killing effect, when 0.6mg/L ozone acts for 5min, 10 3 The killing rate of the cucumber fusarium wilt bacteria, the tomato fusarium wilt bacteria and the cruciferae soft rot bacteria with the concentration of cfu/mL is close to 100 percent. The proper amount of ozone can also improve the nutrition quality of vegetables, and when the ozone concentration in the sewage reaches 6mg/L, the average removal rate of organic matters in the secondary treatment water of the urban sewage treatment plant is more than 80 percent. Ozone itself is a gas without toxic effects, but too high a concentration can also cause plants to be oxidized, injuring plant tissues and affecting their normal growth. After the ozone concentration in the nutrient solution is 0.64-0.72mg/L for 30min, the damage rate of the root system of the cucumber seedling can reach 22.2%; when the ozone concentration in the nutrient solution is 1.157-3.471mg/L, the growth of the water spinach can be damaged to a certain extent.
In order to solve the adverse effect caused by the too high concentration of ozone, when the ozone is actually used for disinfecting the nutrient solution, a method of placing the disinfected nutrient solution for a period of time and reducing the residual ozone amount in the nutrient solution to a safe range for reuse is adopted. However, the solubility of ozone in water decreases with increasing water temperature, ozone is unstable and volatile and decays, uncontrollable properties exist in the process of placing nutrient solution due to the temperature and the characteristics of the nutrient solution, and the ozone disinfection effect is unstable. In the prior art, ozone is directly introduced into nutrient solution to be disinfected through a micro-nano pipeline, and residual ozone in the nutrient solution is blown off after disinfection is completed, and then the nutrient solution is recycled. However, this method requires an additional reservoir, which increases the cost of cultivation; and whether the residual ozone amount in the nutrient solution reaches the safe use standard is judged by an instrument or other modes, and the automation of the disinfection of the nutrient solution is not realized.
